Title: Photoelectric converter
Inventor: SUGAWA SHIGETOSHI
IPC: H04N5/335
Filed: 1987-01-16
Abstract: PURPOSE:To enable the sensors below a shielding part to assure the dark reference output by a method wherein a carrier interrupting means to interrupt any photosignals running in from an opening part is provided between a photosenser below the shielding part and photosensors in an opening part. CONSTITUTION:An insulating film 112 is formed on an emitter electrode to be covered with a shielding film 113 excluding the part for an opening. The shielding film 113 comprising a shielding part 113 is formed above the cells Sd and Sf while the other cells S1-Sn comprise the opening part. In such a constitution, any incident light is converted into an electric signal by the cells S1-Sn while a dark reference signal for dark output compensation is transmitted by the cell Sd. At this time, any excessive carriers running into the dark reference cell Sd are interrupted by the cell Sf formed between the opening and the dark reference cell Sd. Through these procedures, even if an intensive light enters into the photoelectric conversion cells S1-Sn in the opening to make the excessive carriers run out from p base regions 103 to the collector side, the dark reference cell Sd can assure the correct dark reference output constantly.

Title: Device and method for starting power generating facility
Inventor: TSUCHIYA ATSUSHI
IPC: H02P9/08
Filed: 1993-01-19
Abstract: PURPOSE:To cope with the increase in capacity of a generator facility and, at the same time, to nearly simultaneously start a plurality of power generating facilities with one thyristor starting device by making a plurality of inverting sections to correspond to one power rectifying section used for the thyristor starting device. CONSTITUTION:At the time of starting the device, a generator 5 is driven as a synchronous generator which rotates at the same frequency as that of an alternating current obtained by means of a thyristor starting device 1 by supplying a field current to the field winding of the generator 5. With the output torque of the generator, a gas turbine 6 is accelerated until it reaches a self- accelerable speed. A thyrister cylinder device 1 first starts the power generating device connected to an inverting section 1b-1 and, when the starting current becomes sufficiently smaller, starts another power generating facility connected to another inverting section 1b-2 by using one power rectifying section 1a against the plurality of inverting sections 1b. Since the starting current becomes smaller in a short time, the plurality of power generating facilities can be started at nearly the same time.

IPC: B29K101/10
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To provide a branch pipe lining method, with which a branch pipe lining material can be surely reversely inserted in a branch pipe. SOLUTION: A flange part 1B is formed by folding back one end of a hardening resin impregnated part 1A, which is produced by impregnating a tubular resin absorbing material with uncured liquid hardening resin, and then hardening the one side so as to cover the whole outer surface of the hardening resin impregnated part 1A and the whole surface of the flange part 1B or some part connected with the outer surface of the hardening resin impregnated part 1A with a plastic film (or a covering materiel) 2 having a high air tightness in order to form a branch pipe linking material 1 for executing a linking to a branch pipe 11.  Since the inner surface of the hardening resin impregnated part 1A and the flange part 1B of a reversed branch pipe lining material 1 including the boundary part between both the parts is airtightly covered with the plastic film, no pressure fluid such as compressed air or the like leaks through the boundary between the hardening resin impregnated 1A and the flange part 1B at the reverse insertion of the branch pipe lining material 1 in the branch pipe 11 by supplying the pressure fluid in a pressure bag 13, resulting in surely carrying out the reverse insertion of the branch pipe lining material 1 in the branch pipe 11 at all times.

Abstract: PURPOSE:To attain an accurate discrimination without increasing signal processing speed by using >=1 of all path filters so as to shift the phase in the vicinity of a maximum or minimum point of the amplitude of the transmission data and introducing the result to a deciding circuit of a post-stage. CONSTITUTION:For example, the positive polarity of the data is sampled in the vicinity of a peak value depending on the relation between the data rate and a sampling interval, the negative polarity of the data is sampled at a point where the peak value is largely deviated. Then a selector circuit 2 is switched depending on the polarity of the input data and the negative data is subjected to phase control by a variable phase shifting device 35, while the phase of the positive polarity data is kept as it is and the result is introduced to a deciding circuit 6. The data input is detected in a clock-run-in detection 8, the phase control circuit 5 is operated and the coefficient (a) of the all pass filter 3 is controlled depending on the output signal polarity and the level of the selector circuit 2 and the phase characteristic is changed so that the negative polarity data comes, to the vicinity of the peak value. Since the data in the vicinity the peak is always obtained, the deciding error rate is reduced.
